Indeed IP aliasing is your answer. If you are talking about inetd services, then you need to run a separate inetd's i.e.: inetd -a 10.0.0.1 /etc/inetd.conf.10.0.0.1 inetd -a 10.0.0.2 /etc/inetd.conf.10.0.0.2 Most other network daemons also have a way to specify which IP to bind to. named, apache, etc... all do. That should solve your problem. This however opens a question for me: does inetd (FreeBSD -Ww version) allow for multiple /etc/host.allow files? I can think of ugly ways to do this (multiple tcpds?) but just wondering if this has already been done. -Paul.
